A farmer has 140 bushels of for sale at a​ farmer's market. He sells an average of 15 1/8 bushels each day. After 7 ​days, what is the change in the total number of bushels the farmer has for sale at the​ farmer's market?

Question

Write a signed number representing the change in the total number of bushels the farmer has for sale.
  
​(Type an​ integer, proper​ fraction, or mixed​ number.)

Answer 1

The farmer sells 15 1/8 bushels each day for 7 days.

To find the total number of bushels sold, we can multiply 15 1/8 by 7.

15 1/8 * 7 = 106

Therefore, the farmer sells 106 bushels in 7 days.

To find the change in the total number of bushels the farmer has for sale, we subtract the number of bushels sold from the initial quantity:

140 - 106 = 34

The change in the total number of bushels the farmer has for sale is 34 bushels.

Answer 2

wrong

Answer 3

Apologies for the mistake. Let me correct it.

To find the total number of bushels sold in 7 days, we can multiply the average daily sales by the number of days:

15 1/8 = 15 + 1/8 = 120/8 + 1/8 = 121/8

Total bushels sold in 7 days = 121/8 * 7 = 847/8

To find the change in the total number of bushels the farmer has for sale, we subtract the bushels sold from the initial amount:

Change in total number of bushels = 140 - 847/8

To subtract a fraction from a whole number, we need a common denominator.

Multiplying the whole number 140 by 8/8, we get:

140 * 8/8 = 1120/8

Now we can subtract the fraction:

Change in total number of bushels = 1120/8 - 847/8 = (1120 - 847)/8 = 273/8

Therefore, the signed number representing the change in the total number of bushels the farmer has for sale after 7 days is 273/8.
